To @ZZ whom t may concern:

Be it known that I, ERNsr TRIELOFF, of the city of Cassel, in the'Kingdom of Prussia and German Empire, have invented certain new and useful Improvements in Tobacco-Pipes,

of which the following is a specication. i

My invention relates to pipes for smoking tobacco; and it consists `in providing a sectional lpipe-stem with a-nicotineabsorbing plug composed of a `series of perforated felt disks connected together, with the perforations of each disk out of alignment with the perforations of the disk adj acentv thereto, as hereinafter described and claimed.

'In the drawings,f-Figure lrepresents a side elevation of a pipe having my improvements combined therewith. Fig. 2 represents to an enlarged scale a side elevation of a portion of the pipe-stem with the chamber, hereinafter described, for receiving the absorbent material, attached thereto.

irregular locations, substantially as shown,

` tained.

and which are sewed together to `form a completecartridge, as hereinafter described.

A represents the mouthpiece, B the bowl, and C the stem, of the pipe, which latter is constructed in sections, as shown, with an eX- ternal screw-thread, D, at the inner end of each section.

E represents the cartridge-chamber within which the nicotine-absorbing cartridge is conof which it and the sections of the pipe-stem C are connected together, as shown in Fig. 3, withcapability of ready removal from each other whenever it is necessary to clean the pipe, withdraw and clean or 'substitute another cartridge, or for4 any other reason. The chamber E may be formed of any suitable materialsuch, for instance, as horn, vulcanite, Snc. y

Gr represents the cartridge or nicotine ab- Y Fig. 3 represents to an enlarged scale a vertical -section on the line 3` This chamber E is provided at each end with an internal screw-thread, F, by means sorber or collector. This cartridge is composed of a series of woolen felt disks, (shown in plan view bythe diagrams a to h, inclusiva) and each of which have vertical perforations i formed therein in irregular positions, so that Y upon said disks being placed in position with their faces resting against each other, as shown in Figs 3 and 4t, the perforations in each disk will be out of alignment with the perforations in thedisk nekt adjacent thereto. VBy this means the smoke will be compelled to pass between and through the imperforate, as well as the perforated portions of the respective disks, thereby insuring a much more complete and certain filtration of the smoke and the elimination therefrom and absorption by said disks of the nicotine and fluid contained in such smoke.` These disks, when' placed lin juxtaposition, are sewed or otherwise suitably attached together, and thus forma co1nplete cartridge, to the lower end of which is attached a tape, 7c", by means of which the cartridge maybe withdrawn from the cham ber without soiling the lingers, as by the time the filtered smoke has reached the lower end of the cartridge it will be purged from the impurities suspended :therein on its iirst contact with the cartridge. The bore at the upper end of the lower section of the pipe stem is slightly larger than is the bore of the remaining portion of the stem, to admit of the tape resting therein without impedin g the passage of the smoke. The `two disks are de; `signed to be of a circumference correspond` ing, or nearly so, with the inner circumference of the `cartridge-chamber, and when in position the lower end of the cartridge will rest upon and against the upper end of the lower section of the pipe-stem, as clearlyishown in Fig. 3. By constructing the disks forming the cartridge of woolen felt I obtain a nicotineabsorbent which is neither changed by the moisture deposited or by frequent washing' after use. By perforating such disks in the manner described, and arranging said disks together, so that the nicotine and other moisture has an impeded passage therethrough, the

`maximum of filtration'of the` smoke is secured,

and by attaching to said cartridge a tape the same can be readily removedwithout the fin- ICO gers or hand being soiled, and by constructing i the pipe-stem in sections and forming the cartridge-chamber of non-.absorbent material and tion having a chamber, E, and a series of peradapting such chamberand pipe-stem for-ready forated felt disks connected together,'-with the connection With and disconnection from each perforations of each disk out of alignment other the several parts can be readily rewith the perforations of the disk next adj a- 5 moved from each other, cleaned and replaced, cent thereto, substantially as and for the purr 5 and when necessary a newr cartridge quickly pose set forth. and easily placed in position.
